Serial No. 335,728.

I i This invention relates to means for quickly positioning the carriage of-a' card-perforator or similar machine, and partlcularlyrelates to a mechanism for tabulating the carriage denominationally and a key-controlled backs spacing mechanism usable-for correcting a wrong denominational positioning of the carriage. y I

Means for denominationally positioning a card-perforator carriage are es ecially use-- fnl when, the perforator by suita ble coupling means is operated jointly with a typewriting machine in which denominational positioning of the typewriter-carriage is practiced for a counting work. p

Such joint operation is for the purpose of producing perforated ,reco'rd-cards corresponding to data simultaneously typed on a work-sheet in the typewriter. Asis well known, the record-cards are subsequently used in many ways for statistical analyses, I

reports, groupings, etc. A line of data written on the typewriter may include portions which need not be punched in the record .card, and while such portions are being typed the 'perforator must be inactive.

, Heretofore suspension and resumptionof' "joint operation were eifected by pressing or releasing a foot pedal which opened or closed a coupling clrcuit by means of which the two machines were coupled for 'joint 1 operation. By improper or mopportune use of this pedal mistakes are liable to occur.

A further object of this invention, therefore,

is the provision of means for automatically controlling suspension and resumption of joint operation of the two machines, and particularly to provide such controlling means as-shalL be readily settable or adjust;- able and adaptable to such. machines inwhich the carriages are not mechanically coupled.

Another object of the present invention the provision of means adaptable to such machines in which the carriages are not mefi- Toward the end of the cycle A of whether the "typewriter-carriage;return fmovement is initiated automatically by the movement of the typewriter-carriage as it reaches the end of a line or manually by pressing the Manually controllable means are provided to usual carriage-return-key.

make said automatic cycle-initiating means inoperative at will. Heretofore, in combined typewriting and perforating machines it was necessary to operate two keys atthe end of every typewritten line. One key was operated to return the typewriterabarriage and another key was operated to initiate a machine cycle of the card-perforating machine. By the aforesaid means ofthe present invention, both functions may be ac- ..complished by depressing only the carriagereturn-key, or, if the carriage-return move ment is automatically initiated at the end of a typewritten line, no key need be depressed.

T e invention is herein illustrated as applied to a pombined typewriting and cardperforating machine embodying the wellknown Underwood-Hanson bookkeeping ma- 25, 1918, and is equipped with a denominachine and the Powers key-punch. The Powers key-punch, hereinafter ,called the card-1;: lperforator, is substantially of the type tional tabulating mechanism controlled by denominational tabulating keys.

Each machine has a carriage driven b its own spring-motor, and the carriages o the typewriter and card-perforator are, respectively, movable in letter-feeding and holespacing steps controlled by escapement mechanisms. The perforator-carriage escapement mechanism is actuated by the punchselecting mechanism, of which the carriage forms a part. By means which include electromagnets and suitable contact devices in the circuits of the magnets, as, shown in the application of Alfred G. F. Kurowski, Serial No. 48,723, filed August 7, 1925 (now patent No. 1,683,979, dated September 11, 1928), the operation of the typewriter-keys to print also actuates the punch-selecting mechanism, so that punches for subsequently punching 2U holes corresponding to the characters typed are selected. This selection is eflected, as

each key is struck, by depressing and locking a pin over the punch or punches .corresponding to said key. The card at the proper 5 time is raised and those punches which have not been selected rise with the card. The selected punches, held down by the locked pins, penetrate and punch the card by cooperating with a die-plate underneath the card, said die-plate having a hole for each punch. v The card is raised and presentd the punches by means ofa frame which includes the die-plate. and lowered during'a machinecycle of the perforator, which is initiated after the punches have been selected by operation of the typewriterrkeys. Toward the end of this cycle the punched card is ejected from sald 4b frame and replaced by-a blank card. In

the operation of the punch-selecting mecha nism, the perforator-carriage carrying a row of twelve pin-setting plungers actuated by the aforesaid electromagnets traverses the p field of settable pins, of which there is, as

stated, one over each punch; There are forty-five columns of tweIve punches each in the perforator shown herein. The perforator-carriage moves in steps from column to column. At each step a punch or punches may be selected. It will be understood that operation of a typewriter-key may cause two punches to be selected if the corresponding character is designated by twp holes in the same'colu of the card.

Since the punches are caused to be selected by operation of the typewriter-keys, it fol-- lows that the perforator-carriage travels. step by step in unison with the typewritercarriage, on account of the simultaneous ac-, tuation of their respective escapement mechanisms. v V

Heretofore, in combined typewriting and card-perforating machines in which the respective carriages are not mechanically coudl against This frame is raised may be in dissentaneous locations. For expled, no means have been provided foreffecting denominational tabulation of the perfora'tor-carriage corelatively withde'nominational tabulation of the typewriter-carriage.

In this invention, novel mechanism is disclosed for causing a remote controlled perforator-carriage to move automatically at one step a distance greater than a unit feed of the perforator-carriage, to set up a punch in any denominated position horizontally in a vertical zone on the card, in response to the movement of the typewriter-carriage under control of. the denominational tabulating keys. The word denominational is used herein in a generic sense, as it will be understood that the tabulating keys on a typewriting machine (and their corresponding positions on the card) may be called by any 9 names, that is, not only by the decimal names, 4 units, tens, hundreds, etc.-, but, for example, by the names 1, 2, 3, etc.', or the names a, b, 0, etc., or, in fact, by any denominational names that are assigned to them in a predetermiried system. i I, Such means are provided in the present invention, which", in its preferred form, uses the mechanism usually provided in the illustrated card-perforator for efiecting so-called. column tabulation. Said means, as a supplement to this mechanism, consist of novel devices bymeans of which denominational tabulating may be effected.

By providing denominational tabulating mechanism for the perforatorecarriage, as well as for the typewriter-carriage, it is possible to tabulate both carriages'to the same denomination in corresponding zones. It is also feasible, inasmuch as each of the carriages moves by and under the control of its own spring-motor and escapement-mechanism, that the carriages may be corelatively positioned or tabulated in corresponding zones of dissentaneou'sTextents. For example, a card-zone for 'whichthe perforator-- carriage is tabulated may include only four denominational columns, while the corresponding typewriter-work-sheet-zone may have say eight columns, the number of typewriter-zone-columns usually exceeding the number of columns in the corresponding card-zone in order to provide for footing up a total of all the items in the typewriterzone. Furthermore, the corresponding zones on the typewriter-work-sheet and the card ample, two zones on the work-sheet for which there are corresponding zones on the card may be; separated by one or more intermediate zones-for which there are ,no corr'e-j sponding zones on the card. While the type-- .125 writer is being operated for the intermediate zones, the perforatofl-carriage may be caused to remain idle and stationary by means hereinafter explained. .Then, when a the worksheet-zone for which there is a ccr respondin zone on the card is reached, op-

eration the denominational I tabulating mechanisms Wlll cause their IGSPGCtlVGfiQP- 'riages to be tabulated "denominationa-lly and,

it may be, to dissentaneous extents. It may therefore be also said that, by reason of the aforesaid intermediate worksheet-zones, the

zones to which both carriages are now tabulated are in dissentaneous locations, the locations being dissentaneous in respect to the number of zones through which each carriage has moved. a

The usual col mn-tabulating mechanism of the card-perforator includes a key-controlled electromagnet, which, through the usual means, operates ,and sets, a lever to release the carriage from the control-of its escapement mechanism. The escapement mechanism, including an escapement-wheel and pallets, is mounted with said lever on the perforator-carriage. In effecting this release, the operation and setting of the lever disengage the holding pallet from the es capement-wheel. A latch on the end of the lever is caught and held by suitable means when the lever is set, thereby sustaining the lever in its set position. In the ensuing tabulating movement of the perforator-carriage, the latch, movingwith the carriage, encounters a stationary but settable counter-stop and is tripped thereby. The holding pallet thereupon re-engages the escapement-wheel, thereby arresting the carriage and stopping the tabulating movement thereof.

To denominationally position the carriage in the column predetermined by the position of the counter-stoma series of donomina tional stops, one for every denominational tabulating key on the typewriter, is provided, The denominational stops are selectively movable for interception by the counterstops, and are supported in a structure on the perforator-carriage. Said structure 1s mounted so that it moves longitudinally and relatively of said carriage when a denominational stop is intercepted by a counter-stop. A tappet on said structure, as it thus moves, strikes and trips the aforesaid latch.

The counter-stop wliich is usually one of a plurality ofi such stops, is settable along the usual stationary member which, however, is shifted from its regular position in order that the tappet presenting structure, snpporting the denominational stops'may be 1n? terposed between said counter-stops and the aforesaid latch.

Meanscontrolled by keys, which, in the illustrated form of the invention, are the denominational tabulating keys of the typewriter, are provided to select and move a denominational stop corresponding to the operated key. Suitable circuit-closing devices underlying the tabulating keys are provided-and are actuable by said keys $9 close electric circuits, by means of which electromagnets are energized to operate the denominational stop-selecting means. The operation of any tabulating key also actuatesa supplementary circuit-closlng device, which is connected to the usual universal bar operated by the typewriter denominational stops, and is therefore common to all keys. This supplementary circuit-closing device, for reasons to be explained later, is, by 'suitable means, closed during the=first and greater part of the tabulatingkey-stroke, but is open at the end of said stroke. Upon opera tion'of any tabulating key said supplement'ary device closes a circuit to energize the electromagnet which releases the perforator carriage for a tabulating movement, which, as stated, is terminated by means of the denominational stop selected by operation ,of said key.

An electromagnet may be provided for each stop to actuate means to select said stop; a

Like the electromagnets for the pin-setting plungers, these electromagnets are solenoids having movable cores or plungers. Included in the operating connections fromsaid plungers are flexible push-wires. These push-wires are encased in flexible sheaths,

and their number, if, one is provided for' each denominational stop, added to the number of pin-settingpush-wires, forms an aggregate that tends to impede the free movement of the perforator. not move with the carriage but are stationary relatively thereto.

In the preferred form of the present invention, means for selecting a denomina-v tional stop are provided whereby the number of operating magnets and related push- "Wires is substantially less than the number of denominational stops. The typewriter herein illustrated has nine tabulating keys, and nine corresponding denominational stops are provided on the card-perforator.-'

carriage. These stops are in the form of tabs upstanding from arms suitably spaced in parallel array and pivotally supported in the previously-mentioned structure, so

that the edges of the arms of said stops overhe a number of stop selectors also supported in said structure and slidable transversely of and under said edges. A spring on the end of each arm urges rotation of the stops about a common fulcrum shaft, so that the stops tend to move into a I position for interception by a counter-stop.

The magnets do The stop-selectors have formations which normally oppose and prevent such rotation, These formations on each selector are so coordinated to the: formations on the other selectors as to leave an opening for thearm of adenominational stop, which may then rotate only if a corresponding arrangement of the relative positions of the selectors is efi'ected. To effect this arrangement the selectors are relatively moved.

The number of stop-selectors required depends on the number of denominational stops and the number of magnets that may be energized when a tabulating key is oper-,

ated. It will be understood that operation of an inordinate number ofmagnets by one tabulating key is objectionable on account of vthemultiplicity of contacts required. It is preferable to operate not more than two magnets by one key.- v

Agroup of four stop-selectors is arrangeable, according to the well-known formula for combinations, in ten different combinations of their relative positions, not counting their normal positions, if for each arrangement one or two selectors are shifted plunger of which it is connected by means of one of the aforesaid push-wires.

' The arms of the denominational stops being spring-pressed and normally bearing on the opposing formations of the stop-selectors, means are provided to hold said arms 7 clear of the stop-selectors While they are a part of. the tabulating key-stroke.

being shifted. Said arm-holding means are operatively connected to the usual universal member on theper forator-carriage and actu punch-selecting means or by the means that release the perforator-carriage for a tabulating movement. Said carriage-releasing means are operated by a magnet, which, as already explained, is energized during only Atthe end of said stroke, the arm-holding means have reassumed their normal positions, allowing the arm of the selected denominational stop to fall into the opening presented by the stop-selectors that were caused to be shifted during said stroke. The arm of the selected stop remains in thls opening until either a printing key or another tabulating key is operated. Operation of a printing ation is suspended. One of said surfaces be- 115 key causes the arms of all the denomina I tional'stops to be held clear of the stop selectors, which, being spring-pressed, re-

assume their normal positions.

Means for-back-spacing the perforatorcarriage include a'longitudinal member having teeth or notches-spaced according to the steps of the perforator-carriage. Said longitudinal member is mounted so that it may first be movedto engage one of its tooth or notch formations with a suitable projection on the perforator-carriage, and then further moved to effect a back-spacing step of the perforator-carria-ge. The back-spacing movement of the longitudinal member is limited by a stop,- which, in conjunction with proper formation of the teeth or notches on said member, substantially prevents overthrow of the spacing.

perforator-carriage in backlongitudinal member, means operated by an electromagnet are provided. This electro- .magnet by means of a suitable circuit-closwriterscarriage, and it is that part of theback-space key-stroke, incidental to said excess movement, during which the circuitcLosing device for the perforator-carriage To impart the aforesaid movements to the back-spacing solenoid is operated. Thus the typewriter-carriage has completed its backspacing step before a back-spacing movement is imparted to the perforator-carriage. This is a necessary condition if means controlled by the position and movements of the typewriter-carriage are used to automatical- 'ly suspend and resume joint operation of the two machines.

In the present invention the .coupling means between the typewriter and the card perforator includea main coupling circuit. For suspending and resuming joint operation between the typewriter and card-perforator, a circuit-opening device normally closed is provided and placed near the typeopen and hold open the circuit-opening de-',

able either "by he typewriterkey-controlled writer-carriage, and is connected in the main 1 coupling circuit. To cause saiddevice to be vice. The extent, of said surfaces which hold the circuit-opening device open depends on the extent of the zone inwhich oint opercomes an edge if suspension and resumption of' oint operatlon occur 1n two consecutive ste s of the typewriter-carriage.

ncluded in the coupling circuit is the sol back-space the typewriter-carriage, themain enoid that operates the back-spacing means closed. If at this stage it is necessary to in I circuit must be broken before the back-spacing solenoid is energized, or else both carriages will be back-spaced. Therefore, as explained, the typewriter-carriage is backspaced and the main circuit is broken before the completion of the back-space key-stroke, and, since it is during the completion of said stroke that the back-space solenoid is ordinarily energized, the perforator-carriage at said stage of the typewriter-carriage will not be back-spaced.

The typewriter and card-perforator may be used under circumstances requiring a frequent change of the setting of the aforesaid stops, whereby joint operation is suspended, and a large variety in the kind of work done ma, require a large assortment of stops, owmg to the different lengths of actuating surfaces required. There is therefore also shown herein means whereby uniform stops may be used. Such uniform stops are also settable on the typewriter-carriage, and, when said carriage moves'into and out of a zone of suspended joint operation, are effective to rotate a pinion provided for this purpose. A commutator switch'spanning a pair of brush-like contacts bearing thereon is connectedto and actuated by said pinion. said pinion has a limited number of teeth, so that a stop may, in one letter-feeding step of the typewriter-carriage, engage and rotate said pinion and escape therefrom. The segments of the commutator are arranged to alternatejoint operation.

ly' open and close the circuit in which the contacts are connected in successive steps of the pinion. Thus a stop, formed to act as. a tappet to rotate said pinion, may beset at the beginning and another stop at the end of a zone of suspended joint operation, and these stops will,'respectively open and close .said circuit to cause suspension and resumption of said joint operation at the beginning and end of said zone, the stops being set apart a distance corresponding to the extent of said zone. It will be understood that other suitable means to suspend .and resume joint operationmay be used in connection with a pair of uniform stops for each of said zones, theinvention, as related to this feature, residing mainly in the use of uniform stops, irrespective of the particular meansactuated thereby.

Other features and advantages will hereinafter. appear.

parts at the I The -Underwood-Hanson bookkeeping machine (Figure includes the well-known Underwood typewriter mounted upon an adding mechanism 15. Depression of, nu-

meral keys 16 and alphabet keys 17, swingskey-levers 18 about a fulcrum 19 to swing bell-cranks'20 about a fulcrum 21. Said bellcranks swing type-bars 22 about a fulcrum 23 to print against a platen 24. The platen is mounted in a carriage 25 which moves to and fro upon rails 26 and 27 supported in a typewriter-frame 28. A worksheet 29 may be' fed around 'th/e platen by the usual feedrolls 30.

In its advance movement the carriage 25 is pulled by a spring motor 31 and .moves in letter-feeding steps controlled by an escapement mechanism actuated'by a universal bar 32, Figure 6, which in turn is actuated by the heel 33 of any operated type-bar. A rearward extension 34 of the universal bar engages a dog-rocker 35, which has a fixed dog 36 and a loose dog 37 controlling an es capement wheel 38 that is connected in the usual way to a pinion 39, meshing with a letter-feeding rack 40. Operation of any typekey causes the dog-rocker to vibrate about a fulcrum 41, and in this manner actuates the escapement mechanism. space-bar 42 similarly actuates the escapement mechanism by means: of an arm 43, fastened to the space-bar rock-shaft44 actuated by the space-bar levers 44 Said arm 43 engages an arm 45 fastened to the cross-piece 47 connecting levers 46, which support and are actuated by the rearward extension of the universal bar. Saidarm 43, in this manner, actuates the dog-rocker. The cross-plece 47 is pivoted at its ends.

The usual Underwood denominational tabulating mechanism includes a plurality ofdenominational tabulating keys 48 on key-1evers 49, pivoted on a common fulcrum, rod 50. When a tabulating key is depressed, the rear arm 51' of the corresponding key-lever is raised and a denominational stop'52 is thereby elevated, so that its upper end 53 lies in the path of tabulating counter-stops 54. Said counter-stops are settable in a bar 55 mounted between brackets 56 projecting from the typewriter-carriage 25. In a typewriter combined with a computing'mechanism the brackets 56 have upwardly-extendin sides 57 spanned by rods 58 and 59. Setta le along said rods and supported thereon is a computing selector-dog 60 having a tappet 61, which, as the typewriter-carriage .moves along, may engage denominational jacks 62, which are part of the Underwood-Hanson computing mechanism, morefully described in the aforesaid patent to Hart. Said jacks 62 are successively operated byv said tappet as the typewriter-carriage moves step by step through a computing zone. The selector-dog 60 is located andset on said rods 58' and 59 Operation of a to operate said jacks in said computing zone. The denominational jack when operatedcauses a pin-bar, not shown, to be positioned 'so that it may-be indexed according to the numeral-key depressed. Said pin-bar subsequently registers the amount indexed therein in a computing wheel 63, by means fully described in said patent. Underlying the'key-levers 18 and operable thereby, by means of plungers 64, is a plurality of con-' tact devices 65 supported on a plate 66, supported in the typewriter-frame 28. 8

Leading (from said contact. devices" are wires, which, with wires from other contact devices to bedescribed, are gathered in a cable 67, which extends toward the card, perforator to form coupling circuits between said card-perforator and the typewriter. Included in said circuits are electromagnets in'the form of solenoids 68 (see Figure 9), which, when energized, operate the punchselecting mechanism of the card-perforator Thus, whenever a typewriter-key is operated, a. corresponding contact device 65 is closed and one or'more'solenoids are energized.

The punch-selecting mechanism of the perforator includes a carriage 70 mo able in hole-spacing steps upon guide-rails 71 and 72. The carriage is guided upon said rails by means of supper rollers 73 and lower rollers 74 Operation of any typewriter-key causes one or two of twe ve plungers 75, carried by said carria e, to be depressed by means of bell-cranks 6 operated b pushwires 77 encased in flexible sheaths 8, said push-wires being connected to the movable cores or-plungers 79 of the solenoids (see Figure 9) contained within a case 80. The

ments of the perforator-carriage in its holespacing steps, and consists of an escapeme'ntalong. a stationary rack 85. The escapementwheel and its pinion are mountd on the perforator carriage at 86. The escapement wheel 83 has of a pitch suitable to space the perforator-car-riage in steps of hole-spaci'ng extent. -A holding pallet 87 normall holds the'carriageistationary against the pa 1 ofpits spring motor. Said pallet is loosely wheel 83 which, as the perforator-carriage 'moves, 1s caused to rotate by a pinion 8 4 to which it is connected, said pinion rolling mounted" on ashaft 88 adjacent a stepping pallet 89 separate from the holding pallet 87, but capable of'moving the holding pallet by means of a pin 90 which engages an extension 91 of the holdingpallet. Thefstepping pallet. 89i's fastened to oneend of the shaft 88. Said Shea has its bearing in the perforator-carriage,'and upon the other end thereof is fastened a lever 92 having a cam slot 93. A pin 95 on the end of an arm 96, which extends from one side 97 of a bail mem her which includes a universal bar 98, vibrates said lever 92' when said universal bar is actuated. Said universalbar, lying against the bell-cranks 76, is moved whenever one of the plungers 75 isoperated to select a punch, and consequently actuates the escapement' mechanism to hole-space the carria e 70 every time a punch selection is ma e by operation of a typewriter-key. Selection of the punches is effected by means of pins 99. Wherever a punch is to be selected, one of said pins 99 is depressed by its corresponding plunger75 and held in its depressed position by a latch-bar 100 against the reaction of a spring 101, which restores the pin to its normal position when the latchbar 15 released or when another pin related to zo said latch-bar is depressed. There is a latch-- bar for each column of twelve pinsr The pin 99 when depressed opposes the upward move ment of its corresponding punch, said punch being one of a plurality of punches 102 sup-- '25 ported in an upwardly-movable frame which includes a die-plate 103 and another plate 104 that guides the lower ends of 'the punches. The die-plate 103 and the plate 104: areseparated by a gap 105, whichreceives 80 the card to be perforated The perforating is eflected by moving said frame upward. Those unches over which a pin was not depressed the frame and its card, while those punches opposed by the ends of depressed pins pene trate and perforate the card. This perforation is done in. a machine-cycle of the perforator subsequently tothe selection of the punches effected by operation of the typewriter-keys in the manner described. After perforation, the card is ejected by means of rollers, not shown, and deposited in a receptacle 106, while a new card-is being simultaneously fed also by means of rollers intoplace under the punches.

Regular column tabulatioil on perforator herein shown is done by releasing its carriage from the control of its escapement mec anism for a tabulating move- 5o,ment and terminating said tabulating movement by terminating said release. This is accomplished by the usual means, which in-' clude a lever,107 pivoted at L08 upon the perforatqr-carriageT Said lever has a pin 109 which projects toward and underlies a pin 110 in the holding pallet 87. The lever 107 is rotated about its pivot by a bell-crank 111 similar to the bell-cranks 76 and mounted on-the same shaft 112 upon which said bells 6 cranks 76 are mounted. The bell-crank 111 has an extension 113 which overlies an arm 114 on the lever; 107. The bell-crank 111 is actuated by means of apush-wire 115 connected to a plunger 116 of a solenoid 118, which, in the regular card-perforator, is enand latched move upwardly with the cardoccurs when the contacts ergized by closing contacts underlying the usual tabulating key of the perforator.

In the presentinvention these contacts are replaced by other contacts 119. Said contacts 119 are mounted in a suitable case 120 supported by means of a bracket 121 from the rear of the typewriter (see .Figure These contacts are required to. be closed whenever any one of the typewriter denominational tabulating keys 48 is operated, and there is mounted on a shaft 117, which carries the usual universal bar 117 that is actuated by the typewriter denominational stops 52, an arm 122 extending 'rea-rwardly toward tlh case 120. Said case has formed upon one side an upwardly-extendin portion 123, upon which is pivoted a ell-crank 124;,

which, when rotated, will, by means of 'a.

roller 125 made of insulating material, close the contacts 119. Said contacts are normally open and mounted upon the usual resilient strips 119*. This rotation iseffected bythe arm 122 as it. moves upwardly whenever a tabulating key'is depressed. In its upward movement the end 126 of said'arm, after the contacts 119 have been closed, overrides and I passes the tip 127 of the bell-crank lever, which thereu on resumes its normal position under the in uence-of a spring 128 allowing the contacts to separate again (see Figure 13). Thus the contacts 119 are closed during only a part of the tabulating key-stroke,

and for teasons which will be presently de- -87. The wires 129 connect said contacts in said circuit. The lever 107 is sustained in position to hold said holding pallet out of engagement with the escapement-wheel by means of a latch 130 pivoted on-a tab 131 of the lever 107, said latch being caught upon a plate 132 and held thereby until the end of the tabulating movement. The .universal bar 98 is alsoactuated by the bell-crank 111, so that when said bell-crank is operated the stepping pallet 89 engages the escapementwheel and delays the start of the tabulating movement of the carriage until the bell crank reassumes its normal position, which 119 are opened after the end 126 of the arm 122 has passed the tip 127 of the bell-crank 124."

In the regular card-perforator the tabulating movement of the carriageis terminated when a counter-stop 133 intercepts and trips the latch 130, thereby causing the lever '107 Lil? to reassume its normal position and the holding pallet 87 to re-engage .the escapementwheel 83. Supplementing the counter-stops 133, the present invention provides denominational stops by means of which the perforator-carriage is denominationally po sitioned any column predetermined by one of the counter-stops 133. Said counterstops, the same as those heretofore provided, are mounted on the usual notched bar 134 having notches spaced in hole-spacing steps. Said bar is mounted upon the-frame 135 of the perforator. The bar 134 in the present invention has been, by means of extensions 136. (Figure 1), moved upwardly, so that there may be interposed between the counterstops 133 and the latch 130 the denominational stop devices. Said devices include a plurality of denominational stops 137 spaced in a structure- 138 which is mounted upon a bracket 139 supported by the perforator-carriage. The structure 138 is slidable on said bracket bymeansof slots 140, through which applying springs 146 anchored to a springplate 147 fastened to said structure. Said spring 146 on each stop 137 tends to rotate ithe stop and its arm 144 about the rod 143, so that I the stop 137 tends to assume a position in which it may be intercepted by a counter-stop as the carriage moves.

' derlying the lower edges of the arms 144 and extending transversel thereof, have formations 148,'whi,ch, int e normal positions of said selectors, oppose said rotation. Said formations on each selector areso co-ordinated to the formations on the other selectors that, when a proper combination of the relative positions of the stop-selectors is effected,

an opening is presented that will permit the a'rm144 and consequently the stop 137 to rotate. To provide such an opening either one 1 or two of the selectors are shifted from nor- ,mal position.

A group of four selectors afl'ords ten diflerent combinations of their relative positions by shifting one or two selectors, and in each of these combinations the formations on the selectors aiford an'open ing for the rotation of a corresponding denominational stop.

In Figure 8 the denominational stops 137 are designated by numerals from 1 to 9,.1n-

clusive, and t efourstop-selecto'rs 149 are' designated-by the letters A, B, C and D.

The stop-selectors are held in normal positions 'by springs 149. Each selector, slidably mounted in the structure 138, is shiftable by means which include a slug 149 fastened to one end of a push-wire 150 connected at its other end to a plunger 151 of a solenoid 152 contained in the case 152*. The push-wires 150 are encased in flexible sheaths 150*. One or two of said solenoids are energized whenever one of the tabulating keys 48 is operated. To energize said solenoids, there is provided, under each key 48 and operable thereby, a contact device 157, which, when closed, completes a circuit to energize one or two of said solenoids. One of said contact devices is operated and the circuit remains closed throughout the stroke of the tabulating key. Y

The arms 144 bear upon the stop-selectors 149 through the tension of the springs 146, and means must be provided to hold said arms clear of the selectors while said selectors are being shifted by operation of a tabula ting key. As already explained, the bells crank 111 disengages the holding pallet 87 fromthe escapement-wheel 83 when a tabulating key is operated. Said bell-crank also operates the universal bar 98, which, sby means of a link 159, is connected to a lever 153, which may raise a rod ,154 supported by arms 155 fastened to the rod 143, about i which the denominational stops 137 rotate. Said lever raises said rod 154 by engaging an extension 156 of one of the arms 155. The bell-crank 111 and-consequently the universal bar 98,are held in operated position for the greater part of the tabulating keystroke or until the contacts 119 open toward the end of said stroke. In this operated position, by means of said link 159, lever 153 and rod 154, the arms 144 are held clear ofthe stop-selectors while they are being shifted. Toward and at the end of the stroke of the tabulating key, the rod 154, when the contacts 119 open, reassumes its normal position by means of a spring 154 allowing the arm of the selected stop .to fall ,into the opening afforded by the formations of the shiftedstop-selectors. In the mean timea tabulating movement of the perfo-- rator-carriage has been initiated, and the selected stop 137,now moved into eifective W .158 is pivoted at 158 so. that it may be' the spring 142. The tripping of the latch 130 permits the holding pallet '87 to reengage the escapement wheel and thereby ,end the tabulating movement. Said tappet swung upward if 'the'latch is underneath it during a carriage-releasing movement of the lever 107. V I

The Underwopd back-spacing mechanism includes a back-space key 160 on a lever 160 connected to one ,end' of a shaft 161.

To the other end of said shaft is fastened an arm 162, to the end of which is'pivoted a draw-link 163, which actuates the usual Underwood"back-spacing members indicated at 164 and described in the patent to William F. Helmond, No. 930,962, dated August 10,

1909. Said draw-link 163 has the usual long spring-stud "165. Mounted at the side of the typewriter-frame 28 is a bracket 166 extending inwardly and having pivotedat the end thereof a bell-crank 167, which has a forked arm 167 which engages the spring stud 165 When the back-space key is op-' erated and the draw-link 163 pulled downwardly thereby, saidbell-crank rotates about its pivot, and the end 168 thereof, toward the end of-the back-space key-stroke, closes contacts 169. Said end 168'is in the form of a roller or button made of insulating material. Said contacts 169 close a circuit to energiae a solenoid 170, Fig. 7, to operate means for back-spacing the perforator-carriage. Said contacts 169 are mounted on the bracket 166 and suitably insulated therefrom. Pivot-ally connected to the plunger 171 of said solenoid 170 is one end. of a link 172."

. The other end of said link is pivotally connected to a bell-crank lever 173 pivoted upon' a bracket 174 fastened to the perforatorframe. By means of a spring 175, said bellcrank 17 3 is held in normal position against a pin 17 6 driven into said bracket. Said bellcrank 17 3 when rotated by the solenoid 170 causes a toothed bar177 to rotate about a nions 180 bearing in brackets 181 and 182 -ble movement, the bar is provided with trunfastened Q he perforator-frame. Said trim- I nions are also slidable longitudinally in said brackets so that the bar may move in a backspacing direction. A shoulder 184 of the trunnions stops against the side of the bracket 182, and thereby limits the backspacing movement of the bar. With proper formation of the teeth 17,8 andthe endwise movement ofthe bar thus limited, overthrow of the perforator-carriage in back-spacing is substantially prevented. In order .that the bell-crank 17 3 may'swing the toothedbar 177 into engagement with the projectingmemben 179, one trunnion member of said bar is provided with a cam-block 183 engageable by the rounded ed e 185 of an arm 186 of the bell-crank 173. aid edge 185 working against a suitably-inclined cam-surface of said block, causes the bar to rotate about its trunnions until one of the teeth 178 engages theprojecti'ng member ment of the bell-crank, at the beginning of which the edge 185 haslencountered a shoulder 187 of the cam-block, causes a back-spacing movement of the barwhich'is transmitted to the carriage and is completed, as shown in Figure 20. Figure 18 shows the toothed bar 177 in its normal position inwhich it is held by an obliquely-pulling spring 188,

effective to swing the bar about its trunnions and disengage it from the projecting memher, and the other component bein effective to h restore the bar after a bac -spacing movement by sliding it along the trunnions 180. Figure 21 shows an alternative construction of a toothed back-spacingbar 190.-

1n .redession of said teeth from said member when the, bar is disengaged. The teeth in any form of bar are spaced according to the hole-spacing steps ofthe perforator-carriage.

.179, as shown in Figure 19. A further movek the pull of which has two components, one being Included in the main circuit supplying the solenoids, by means of which the card-perforator and typewriter are coupled, is a contact device 191normally closed and connected in said circuit by means of wires 192. Said contact device is supported by a bracketv193 I fastened to. a. casing 194, which forms part of the computing mechanism. Bearing in.

said'bracket is a plunger 195, which bears upon an insulatedextension 196 of a resilient member 197 of the contact device. 'Whensaid plunger is in depressedposition, the contacts 198 are open and the main circuit thereby broken. lWhensaid circuit is broken, joint operation between the typewriter and the card-perforator is suspended. This suspension of joint operation is necessary while writing certain portions of a line of data on p the work-sheet in the typewriter if said porthe card.

tions of the data are not to be transferred to To automatically. predetermine when such joint operation must. be suspended, there are provided stops 199 movable with the typewriter-carriage and so spaced as to override and depress the plunger 195, and there-' by cause the aforesaid main circuit to be open while said portions are being written. Said stops are set along a notched bar 200 similar to the bar in which the regular typewriter tabulating counter-stops are set. Said notched bar 200 may be supported between brackets 201 fastened to the upstanding sides 57 of the brackets 56. Said stops 199 have surfaces 202 of varying lengths corresponding to the extent of the zones in whiph jointoperation is to be suspended. If joint operation-is to be suspended for one step of the typewriter-carriage and resumed in the following step, one of said surfaces must be an edge 203, see Figure 4. Inclined camming edges 204 facilitate the depressionof the plunger 195. 7

In the step in which the typewriter-can riage moves from a zone in which joint op-' eration was suspended, the surface or edge passes from the plunger 195, permitting the contacts to close, so that the next stroke of a typewriter-key also operates the cardperforator mechanism. In said step thetypewriter-carriage alone moves. If, at the end of said step, the typewriter-carriage is to be back-spaced by operating the backspace key 160, the contacts 198 must be opened before the stroke of the back-space key can close the contacts 169, or else the perforator-carriage will be back-spaced also.

' movement in the back-spacing step of the typewriter-carriage, and it is preferably during the poption of the stroke of the backspace key incidental to said excess movement that the contacts 169 are closed.

The, well-known Underwood carriage-return mechanism as applied to the Underwood-Hanson bookkeeping machine is driven b the motor, not shown,'of said bookkeeplng machine. A belt 205 runs from said motor to a 'pulley 206 fastened to one end of a shaft 207; which has its bearing in a bracket 208 supported on the typewriterframe 28. Keyed to. said shaft is a clutchmember 210 which is sl'idable on said Shaft 207. Said other clutch-member has pinionteeth 211 which mesh with and drive a rack 212 fastened to the typewriter-carriage 25.

'Ihe clutch-member 210 is slid into engage mentwith the clutch-member 209 by means of a lever 213 fastened to a shaft 214. The

engagement of said clutch-members may be effected automatically as the carriage moves in the last letter-feeding step which terminates a line of Writing. In said last step a link 215 is caused to be thrust downwardly by means shown in the patent to Richard F.

Hoyt, No. 1,238,919, dated September 4, 1917.

As said link is thrust downwardly, it depresses one end of a lever 216 mounted on a pivot 217 fastened in the typewriter-frame 28. The otherend of said lever as it rises encounters a pin 218 fastened in the side of a link 219, and thereby raises said link 219, so that a notch 220 on said link escapes from its holding edge in a plate 221. -The link 219 thus freed is pulled rearwardly by a spring 222, and, by means of an arm 223, rotates a shaft' 224. Said shaft 224, by means of an arm 25 and a link 226, rotates the shaft 214 toe ect engagement of the clutch-members. In this manner the clutch-members are automatically engaged after the carriage has taken its last letter-feeding step, and the carriage is then returned to its starting place.

At the end of the carriage-return movement, means, shown in said patent to Hoyt, rotate a shaft 227, and said rotation, by means of links'228 and 229, 'is transmitted to the shaft 214 to effect disengagement of the clutch-members.

A carriage-return movement'may be also initiated by depressing a carriagdreturn key 230, which is mounted upon a lever 231 pivoted to the typewriter-frame 28 at 232. An arm 233 of said lever as it vibrates raises and frees the link 219 to actuate the train of parts described. Simultaneously with the engagement of the clutch-members 209 and 210, contacts within a case234 are caused to be closed by the rearward movement of a bar 235 connected to the shaft 224.

Means whereby initiation of a carriagereturn movement also causesa cycle of the perforating machine to be initiated are 'pro vided. Said perforating cycle is usually initiated by a perforator trip-key 238 at the typewriter keyboard, which, when operated,

closes contacts'239, see Figure 9, to close a circuit to energize the usual solenoid 240. Said solenoid 240 when energized releases clutch-member 241, (Figure 17 on the per forating machine. Said clutch-member 241 4 when released couples a main driving shaft 242 of the perforator to a driving disk 243 geared to a shaft 244 of a motor generator 245. Said main driving shaft has a commutator 246, which, toward the end of one revmember 209 engageable by another clutcholution of said shaft, bridges contacts'247 return movement is'inltlated, said extension- 248 when energized trips a clutch-releasing member 248 to engage a clutch 249 by means of which the usual perforator carriage-returnmechanismof the card-perforator is engaged to effect the return of the .pertorator-carriage 70.

An extension 250 (Figure 16) is added to the arm, 223. When a typewriter carriageswings rearwardly, and its ,tip' 251 sweeps over an arm-252 of a bell-crank 253, and thereby rotates said bell-crank, which is pivotally mounted on a plate 254 fastened to the typewriter-frame 28. The bell-crank 253 is held in normal position by a spring 255 which normally pulls in a line passing through the pivot'center-of the bell-crank, so

that said spring is effective to return the bellcrank to its normal position, irrespective of the direction of rotation of thebell-Crank.

As the bell-crank is rotated by the rearward sweep of the extension 250, a roller 256 thereon, made of insulating material, closes for a moment the contacts 257. Said contacts 257,

as already stated, bridge the contacts usually.

' direct current, which maybe supplied by responding to 4 one end of which is formed a six-tooth pinactuated by the regular perforator trip-key 238. A switch 259 may be provided and connectedin a bridging circuit 260. When said switchis open the contacts 257 are inefiective to energize the solenoid 240, and consequently, when a typewriter carriage-return movement is initiated, saidsolenoid will not be energized when said switch is open.

All solenoids herein mentioned are preferably designed to operate on a low voltage the motor generator 245-.

Figure 22 shows means whereby the main circuit may beopened and closed to automatically suspend and resume'joint opera tions, said means being one way of enabling the use of uniform stops. There maybe provided accordingly a bar 265 which would replace the bar 200, and; on said bar, unlform stops 266 may be set in positions corhe beginning and end of a zone of suspended joint operation. I A bracket 267 may be fastened to the casing 194 in place of the bracket 193; Said bracket 267 forms a bearing for a shaft 268, upon ion269. Said stops 266 have tappet formations 270, whereby, as the typewriter-carriage moves, 's'aid pinion may be rotated. The number of-teeth of said pinion 269 IS limited preferably to six, so. that, in ;one

' letter-feeding step of the typewriter-carriage, said tappet formations may engageand rotate said pinion one step and escape therefrom. A spring-pressed detent 271 lightly presses between adjacent teeth of the pinion and locates said pinion at each step.

. To the other end of the shaft 268 is fastened ducting material, each 0 which may bridge through the brush-like contacts 273 and close a main circuit. Said segments are suitably insulated 'from one another and from the machine. The commutator should be made as light as possible to prevent overthrow due toinertia. Said contacts areconnected inthe main circuitby means of wires 274. It will be seen from Figure 22 that said main circuit may be alternatelyopened and closed by successive steps in the rotation of the pinion 269. Thus a stop 266 properly-set will, in the step in which the carriage moves \into a zone of suspended operation, rotate said pinion and cause the circuit through said contacts and one of said segments 272 to be opened as said segment 272 is rotated away from said contacts. In the step in which the carriage moves out of said zone of suspended ]oint operation, another stop, properly set, will rotate the pinion 269 through another stepfbringing the succeeding segment under the contacts. The stops 266 are set apart a distance corresponding to the extent of the zone in which joint operationis to be suspended,

a pair'of stops being used to define the beginning and end of each zone.
